RT Journal Article SR Electronic T1 MR Imaging of an Infiltrating Spinal Epidural Angiolipoma JF American Journal of Neuroradiology JO Am. J. Neuroradiol.

In this report, we present the MR imaging findings of a pathologically proved infiltrating spinal epidural angiolipoma that appeared largely hypointense on T1-weighted images and enhanced strongly with IV injection of contrast medium, features that suggested a malignant tumor.
